Recent related posts show how recurrent these high-wind events have been across Southcentral Alaska this year and how quickly impacts escalate. Earlier in the month, winds up to 84 mph in Palmer and 75 mph in Wasilla cut power to more than 21,000 MEA members and prompted the Red Cross to open a shelter in Palmer, with additional outages on the Kenai and in Anchorage as debris and non-functioning signals created hazards (Red Cross opens Palmer shelter amid Mat-Su windstorm power outages and Wasilla multi-family fire). A day later, outages still affected about 20,000 households from Glacier View to Knik Goose Bay Road, with some rail crossings disabled by wind damage (Thousands remain without power as winds roar through Mat-Su). Earlier-year storms brought even higher peak gusts—over 100 mph in places—and combined wind and rain that led to flooding advisories, avalanche warnings, and widespread infrastructure impacts across Anchorage and the Mat-Su (Wind and rain batter Anchorage and Mat-Su, leaving power outages across the region; 80 mph, 90 mph and higher: Here's a rundown of peak gusts recorded across Southcentral Alaska in Sunday's storm). Similar wind-driven disruptions in prior seasons have closed schools, strained utilities, and triggered emergency declarations, underscoring the pattern of severe bora wind events in the Mat-Su and adjacent areas (Icy roads close Su Valley schools after high winds cause outages in Anchorage and Mat-Su; Mat-Su schools closed Tuesday after blizzard hits power lines, highways; Dunleavy issues disaster declaration for Interior Alaska and Mat-Su storms; Palmer digs out from major windstorm that prompted emergency declaration).
